SQL Server 2016: Identify Regressions with Query Store
SQL Server 2016 offers a new tool for performance tuning called Query Store. This holds metrics that let you quickly see when an execution plan change has negatively impacted the database.
SQL Server 2016: Live Query Statistics
A database query times out and you don’t know why. The estimated query plan is revealing the problem, so you remove the timeout entirely. An hour later it is still running and you are no closer to getting the actual execution plan. If only there was a way to find out what is actually happening inside the server. With Live Query Statistics in SQL Server 2016 you can now answer that question.
SQL Server 2016: Dynamic Data Masking
Data masking is a necessary, but error prone process. You only need to forget the mask one time to leak sensitive data. SQL Server 2016 attempts to address this with a feature called Dynamic Data Masking.
SQL Server 2016: Row-Level Security
A common criticism for SQL Server’s security model is that it only understands tables and columns. If you want to apply security rules on a row-by-row basis, you have to simulate it using stored procedures or table value functions, and then find a way to make sure there is no way to bypass them. With SQL Server 2016, that is no longer a problem.

SQL Server 2016 seeks to make encryption easier via its new Always Encrypted feature. This feature offers a way to ensure that the database never sees unencrypted values without the need to rewrite the application.
